INVESTIGATION OF DIFFUSION FLAMES (ISSLEDOVANIE DIFFUZIONNYKH PLAMEN),
Abstract
The paper discusses the results of comprehensive theoretical and experimental studies of diffuse combustion in laminar and turbulent gas currents (jets). The study covered: (1) the combustion of unmixed gases within laminar plane-parallel boundary layers; (2) the combustion within plane-parallel boundary layers in the sub- and supersonic effluent velocity regions; (3) the combustion of axially-symmetrical and plane gas flames with given initial velocity (momentum), temperature, and concentration distributions; and (4) the combustion of axially symmetrical turbulent flames of finite dimensions spreading within a wake homogeneous current. The results confirmed the basic assumptions of the aerodynamic theory of gas flames, and the methods of the flow theory applied to the calculation of gas combustion allow the development of efficient approaches to the aerodynamic design of gas torches. The article also offers numerical results in the form of graphs and tables which may be utilized during engineering designs. (Author)
